Re: pneumatic catapults

Multiple small cylinders filled through the same solenoid valve will fill no faster than a single large one (and perhaps a bit more slowly, given the tubing required). I presume that Billfred is providing this in light of the recurrent rule:

That is, multiple smaller cylinders, EACH FILLED THROUGH A SEPARATE SOLENOID VALVE, will fill faster than one big one filled through (as required by the rules) one solenoid valve.
